Protein Effect | loss of function |
Gene Variant Descriptions | RAD51D S207L lies within the Walker B motif of the Rad51d protein (PMID: 28646019). S207L results in impaired homologous recombination, as demonstrated by disruption of the interaction between Rad51d and Xrcc2 and decreased Rad50 accumulation in response to DNA damage in cultured cells (PMID: 28646019). |
